Rims for wheels specifically created for the new breed of adventurous thrasher go-anywhere drop-bar bikes designed to work with multiple wheel and tyre sizes.

19 DEEP | 29 WIDE Ext | 25 Wide Int | 400G

Key features of this rim that make it great for the focused purpose of drop-bar adventure/gravel road riding are:

  • Wider 29mm external/25mm internal rim provides excellent ride handling and support for wider tyres and they work perfectly with up to 2.3” MTB tyres. 
  • The 19mm deep rim delivers excellent strength needed for the lower spoke counts and higher gear torques from road groupsets when compared to MTB setups.
  • Asymmetric rim accommodates the front disc and rear cassette hub offsets and helps build an even stronger and more durable wheelset thanks to balanced spoke tensions.
